JAMES SINCLAIR AND JOHN SELLERS, OF JONESBOROUGH, TEXAS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 548,277, dated October1895.

Application filed September 21, 1894. Serial No. 523,684- (No model.)

To aZZ whom it may concern.-

Be it known that we, JAMES SINCLAIR and JOHN SELLERS, citizens of theUnited States of America, residing at Jonesborough, in the county ofCoryell and State of Texas, have invented certain new and usefulImprovements in Plows, of which the following is a specification,reference being bad therein to the accompanying drawings.

This invention contemplates certain new and useful improvements inplows; and it has for its object the production of simple and highlyefficient means for regulating the depth of penetration of the plowsharein all kinds and conditions of soil.

To this end the invention consists of a bar or shoe extending from theplow-standard and designed to trail in the rear of the plowshare toregulate the depth thereof.

The invention further consists of a bar or shoe secured to theplow-standard and extending rearwardly therefrom, and straps for holdingand adjusting said bar or shoe at the desired point.

The invention still further consists of a rear plate or runner attachedto the nether side of the bar or shoe to sustain the latter and preventits too great penetration. when plowing sandy or black soil. This runneris broad and obtains an extended bearing upon the ground.

The invention also comprises the details of construction, combination,and arrangement of parts, substantially as hereinafter set forth, andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation ofour improved plow. Fig. 2 is a top plan View of the same. Fig. 3 is arear end view thereof with the plowshare removed. Fig. 4 is a View inperspective of a portion of the standard and the depth-regulating bar orshoe and the runner.

Referring to the drawings, A designates the plow-beam, a the handles,and a the standard, which is preferably in loop form. This standard isfirmly held in position by inclined braces a, secured thereto and tobeam A.

B is the depth-regulatin g or bar shoe, which is pivotally held at itsinner end within the standards by a nutted bolt b, which also unites thelower ends of braces a. to said standard. This bar or shoe isogee-shaped,

and to its free or rear end I) are connected the lower ends ofadjustable straps C, said straps being united to said arm by a nuttedbolt 12*. Those straps are provided with a series of holes oropenings 1) therein, through plowshare can be further regulated, greateror less tilting being thereby obtainable. There will be provided twostandards D, one on each side of the beam A.

The advantages of our invention are apparent to those skilled into theart to which it appertains, and it will be specially observed that wehave provided simple, inexpensive, and highly-eflicient means forregulating the depth of penetration of the plow-point, and that theparts are free from all complication and not liable to get out of orderor be deranged.

The wear-plate or runner F is curved in its length and conforms to therear end portion of the bar or shoe, and is secured to the latter in anyconvenient manner, preferably by having hooksf at its forward end, whichengage with lateral projections g on the shoe, and by projections h atthe rear end, which engage with a pin or fastening 't' on the shoe. Thisrunner is detachable and is used when plowing sandy or black soil toprevent the shoe from sinking into the soil to too great a depth.

We claim as our invention- 1. In a plow the combination with the plowshare and standard, of an approximately ogee shaped runner pivoted tothe standard at its forward end, and a brace for vertically adjustingits rear end, of a shoe conformed in its length to the outline of thelower edge of the runner and detachably connected there- 'with by endfastenings, substantially as set forth.

2. In a plow, the combination with an approximately ogee shaped runnerarranged to I to engage with the fastening at the rear end 1'6 trail inthe rear of the plow share to regulate of the runner, substantially asspecified.
